Recently I've been talking to a lot of people new to the Orthodox gay scene, whether in the closet or out, they are first beginning to understand who they themselves are. To you, and all my friends-gay and straight, I have some advice:
Your sexuality is yours. You have the right to do with it what you feel is best for you. If a straight person wants to get married, great, if he wants to stay single, that's fine too, even though Orthodoxy may encourage you to get married as son as possible. For a gay person- if you need to be in the closet, do that. If you need to be out of the closet do that. if you want to marry a member of the opposite gender- I do not really support that, but just make sure you take into account other people's feelings and emotions when doing it.
Sexuality is fluid. For many people it is ever changing, from curiosity to bisexuality to homosexuality and back again. And there's nothing wrong with that. The important thing is that you stay in touch to who you are- and you focus on what you really want from your life. Understand where you fall on the "spectrum" and how that plays in to your life. You sexuality is yours, to know, to understand and to do with it what you feel best. When someone is in the closet, many people try to encourage them to come out and many people try to force you to stay in there, especially in the Orthodox world. So again, try to know what is best for you, and don't let anyone else force you to do anything one way or another.
